I don't know how to load it. It drops to 6.3V right away.............on a 4 cylinder motor!!!!!!!!!!! I just want to be sure I'm not doing something wrong or motor is locked, which it's not. I want to be sure it's not the remote relay. The old starter kept gradually dragging and I kept charging battery, thinking starter. I "rebuilt" it. I think it was the battery all along. I can get a free new one at Costco but I gotta know if it breaks down to feel better. I guess if I get a new one that will tell me. Going to try and find a person who knows how to use a load tester tomorrow.
I should have known it was the battery, I am losing my common sense. The darn thing kept charging up good. My battery charger has NEVER overcharged a battery to 15V. I have NEVER heard of a bad battery showing 15V and then 12.6 within minutes between testing. So I blew off this info. But now the fight is on.

Like you said the internet says 9.6V min during starting. I just didn't know if that is reliable the way I did it.
